o A :fvwm t may concern `known that l, VVInLiAivi O. Fnsn'r, a

citizenoitV the United States, residing 1n.

Hackensack, county of Bergen, and'St-ate of New Jersey, haveinventerd ordiscovered certain new or useful Improvements in Ozone-Generators, ofwhich the following is a full, clear, and complete disclosure.

Mv ot' a kind suitable for use in producing ozone in small quantitiesand of relatively low con centration torV purifying the air ofapartments and for other uses where only low concentration and limitedquantities are desired.

The object of my invention is to provide a compact, durable, reliabledevice for such use which can be cheaply manufactured and the parts ofwhich can easily be assembled and removed for repairs should they becomedamaged.

l trodes are In the drawing accompanying and forming a part ot" thisspeciication, l have illustrated one embodiment of my invention.

In this drawing Figure l is a longitudinal vertical section of thegenerator. Fig. 2 is a transverse section taken on the line 2-2 ofFig. 1. Fig. 3 is a transverse section taken on the line 3 3 ot `Fig. l.Fig. 4f is a detailed view showing one of the dielectric plates forminga part of the generator.

Referring in detail to the generator shown in these views, the numeral ldesignates a base ot any suitable kind on which the generator is mountedThe generator comprises a plurality of ring-shaped electrodes 2, 8, 4, 5and 6, spaced apart and in line with one another. The electrodes 2, 4and 6 are provided with radial extensions 7 (see Fig. 3) whichextensions are attached to the elongated strips 8, three in number, andthe elecheld in fixed 'relation by these strips. The 'electrodes 3 and 5are held in position by the insulators 10 which are attached at theirinner ends to the lugs?) on the electrodes and at their outer ends totheelongated strips S. The electrodes are all spaced from one another so asto leave air aps 11 between them and a r1ngshaped dielectric plate l2 ofglass 0r other suitable material is' located in each of the air gaps.The electrodes 3 and 5 are connected by means of the' binding post 13with one side ot a source ot electric current or a suitable voltage foruse with Aa machine ot this kind invention relates to ozone generatorswill pass through tween the adjacent edges ot the e and the electrodes2, 4 and G are connected, as shown, to the other side off' the samesupply. Thedischarge takes place through the dielectric plates betweenthe oppositely 'disposed edges 14 of the ring-shaped electrodes in orderthatV the ozone-.may he properly diluted or mined with the air which itis intended to-p'urity, each'o the electrodes isprovided with airopenings, l5

located adiacent the edges of the electrode and distributed around the.circular wall of the elect-rode so that air may enter through theseopenings and mingle with vthe ozonized air. The dielectric plates eachhave` open centers 16 and the electrode 2 is provided with' a largeopening 17.disposed opposite the small opening 18 in the electrode 6.The 'operation of the generator is as :tollows: A suitable fan or bloweryis arranged to drawl air through the opening 17. This causes air 'fromthe outside to enter the generat-or through the air gaps lso that it theelectric discharges belectrodes and be ozonized; Additional air entersthrough the openings 15 and the small opening 18 and-mixes with thezonized 'air and is purified. The mixture is thus made suiicient-lydilute for use in living compartments vWhere a high concentration wouldbe objectionable. I have indicated the iiow of air through the device bymeans'o arrows. While l have not shown the saine, it is to be understoodthat the generator, because ot' the high voltage employed, is preferablyincased in a suitable insulating or 'grounded case so as to prevent acciental contact therewith. The dielectric. plates are the only parts ot amachine of' this hind which are liable to be damaged and, should thishappen, these plates can easily be removedl by removing one of thestrips 8, which permits the damaged dielectric plates to he` lifted outot the generatorl and new plates inserted.

Having now described 'my invention and mode of its use` what l claim is:l

l. Tn a device of the kind described, 'a plurality of hollow electrodeshaving perforation in their: walls and spaced from onefv fixed relationby strips extending alongand secured to their outer walls, substantiallyas described.

l 3. In a device of the kind described, a plurality of ring-shapedelectrodes spaced apart and in line with one another and held in fixedrelation by strips extending` along and secured to their outer walls,and die/led tric ring-shaped plates interposed between said rings,substantially as described.

4:. ln a. device et the kind described, a plurality 'of parallel strips,a plurality ef ring-shaped electrodes attached directly to said strips7and a plurality of ring-shaped electrodes interposed between andalternating with said first named electrodes and secured te said stripsindirectly by means ci insulators, substantially a described.

5. ln a device of the kind described, a plurality et ring-shapedelectrodes spaced apart and in line with one another and held in fixedrelation by strips extendingl along and secured te their cuter walls,and dielectric rings-halved plates interposed between said rings, saidelectrodes having air clienings adjacent their edges, substantially asdescribed.
